It was only a moment, a single solitary moment. Had he not been paying attention he may have let it slip by him and fade into the next moment. But the Dread Lord misses nothing, ever vigilant, ever on guard. Sitting alone in his private chamber, a quiet somber place made entirely of the same black stone as the rest of the castra, Vae sat in quiet meditation when the moment passed. Somehow the air tasted differently, his armor carried more weight than usual, even the weight of his sword seemed in balanced for some reason. Whatever place or time he found himself in there was no more familiarity and the Imperium had to forge ahead. His slow heavy footfalls echoed through the halls as he passed his Legionaries who paused momentarily for a quick salute before continuing. As he appeared looking on the balcony over looking the great expanse that was his domain the thunderous footsteps of thousands of soldiers echoed throughout the blackened cavern as they moved through formations and carried out whatever tasks were asked of them.

He had little time to think more on it as he marched into the Throne Room where the other Chapter Keepers and a handful of others were already gathered. An eclectic mix of character there was more that had to be discussed later,
"Vae Dheyer, Commander of the White Legion. What is thy bidding my master?"
